I posted this over at the 1911 forums, also seeking some advice here on this problem
Old family pistol, I worked on years ago, but had a pitted bore.
I sandblasted all the parts with the exception of the hammer, sear, and main spring, which I had hard chromed. I filled the pitted areas in with JB Weld, sanded and coated with Norrells Moly Resin.
I ordered a new barrel from Gun Parts Corp/Numrich Arms, which I received today. Tinkered with the barrel , it fit snug but worked, so I went to test fire the pistol.
There were many rounds going off when the slide cycled without me pulling the trigger, when the slide went into battery, even when I retracted the slide, one round fired. I was in a isolated area on my property, after one magazine, called it quits. Just glad I did this at my shooting area instead of near home. My confidence in this little pistol left after this happening.
Aside from replacing all the fire control parts, what should I look for in the cause of the problem? Disconnector? Sear? The firing pin is working properly, not stuck or hanging.
If it had been a feeding or ejection problem, I think I could have corrected that, but a slam fire or accidental firing is dangerous.
And being a concealed hammer, little bit harder to diagnose.
I realize this does not pertain to Sigs, perhaps some members have had experience with this little pistol.
Any advice or input on a fix would be appreciated.

Weak firing pin spring... or broken?

No, the two piece firing pin is floating correctly when I checked it after I got home and dissassembled the pistol.
My version does not have the half cock notch in the hammer.

Did it work properly before you started fixing it up?
I'd guess the refinish job on the hammer and sear somehow reduced the amount of engagement and/or altered the engagement angle of the two parts.This message has been edited. Last edited by: arfmel,
No good deed goes unpunished.
I would be looking at the sear / hammer too. Especially given the age of the gun. Lots of wear over the years, possibly.
